The series premiered in
1999. Stopped in 2004 after 26 issues, but was continued titled Case
Files: Sam & Twitch from 2003 to 2006 (additional 24 issues).

The series
describes the work of two hardcore homicide detectives in New York's
police force. They are Sam Burke, who is mostly seen as the brawn and
the slightly more cynical character, and Maximilian Steven Percival
'Twitch' Williams, who is regarded as more of the brain and the better
mannered character.
